kwalk don't you have a pre-facelift? Those angel eye bulbs would NOT work in your housings if so because you don't have stock angel eyes. They are meant for facelift lights equipped with factory rings.
As for the running boards, considering with shipping those aluminum "boards" are more than half the price of the aftermarket, OE replica boards:

And those metal strips are over 1/3 the cost of Genuine BMW running boards:

I wouldn't waste my time with them at $300+, I'd just as quickly take the aftermarket OE replica boards at $500 and take my chances, at least those give the wider look of the running boards, and the rubber inserts for grip as they should be functional in addition to aesthetical.
